7 Claims.

hinges and usually terminates in quite a sharp The or substantiallyvertical curve at its rear. deck lid when closed presses down upon, andis sealed completely around its periphery by a rubber Weatherstrip. Dueto the fact that the deck lid is a thin sheet steel stamping having theabove described curvature, the lid tends to crinkle if not provided withthe correct lock.

It is the object of this invention to produce a simple deck lid lockwhich will draw the lid.

into sealing relation with the Weatherstrip and place the lid undertension rather than compression and thereby avoid crinkling of the lidwhen locked.

Referring more particularly to the drawings,

there is shown a portion of the rear deck of an automobile bodycomprising outside sheet metal panel I and inner sheet metal panel 2.The lid is provided with an overlap flange 3 (Fig. 8) which presses andseals against a rubber weatherstrip 4 which extends completely about theperiphery of the opening in the rear deck 5. Figs. 8 through 11 show thelower horizontal edge of clockwise, Fig. 7, thereby drawing links 30lip-- the deck lid, that is, the end most remote from the front edge,not shown, which is hinged to the body.

The deck lid locking arrangement comprises a pair of locks operated by asingle deck lid handle Ii. Only one look will be described because thetwo locks are identical. The lock comprises a support plate 8 which isfixed to the inner panel 2 in any suitable manner, such as by welding orbolts. The plate 8 has a vertical flange I which projects outwardly fromthe inner panel 2, as. shown in Fig. 2.

The latch bolt is designated 9 and the bolt head takes the form of ahook Ill. The bolt 9 is positioned between the legs II and I2 of theyoke I3 and pivoted on pin I4 which is fixed to legs II and I2. A pin 22is journaled in flange I. Yoke I3is fixed to pin 22 on one side of theflange l and lever 23 is fixed to the yoke on the other side of theflange. The bolt is biased downwardly by spring I5 carried on pin I4,the lower end I6 of which hooks over bolt 9. The bolt 9 is provided withlug I! which abuts corner I8 of flange I to limit the downward swingingoi bolt 9 when the lid is raised and the bolt head It! disconnected fromits keeper I9. The keeper I9 is fixed to bracket .20 which is fixed tothe rear deck panel 5 adjacent the lower edge of the rear deck opening2I.

The swinging of each bolt is effected by rotation of handle 6. Handle 6is journaled in a bracket 24 fixed to the inside lid panel 2. A lever 25is fixed on the handle spindle 26. A pair of links 2'! connect the lever25 with levers 28 which are pivotally mounted on plate I by means ofpins 29. Link 30 connects lever 28 with lever 23.

In Figs. 1 and 8 the lock is shown in locked position with the bolt headI!) interengaged with keeper I9. 7 To open the lid the handle 6 isturned so that lever 25 rotates counterclockwise, Fig. 1. The push thusexerted on links 21 causes the lever 28 on each lock to swing clockwise,Fig.

3, which, through link 30, swings lever 23 counterclockwise as viewed inFig. 4. This causes yoke I3 to swing counterclockwise, Fig. 4, whereuponthe yoke strikes the tail 32 of bolt 9 causing it to rotatecounterclockwise and disengage the bolt head I0 from the striker asshown in Fig. 9.

The locking of the lid is effected as follows: The lid is closed untilit rests against the eatherstrip 4. At this time the lid is usually notcompletely closed as ilustrated in Fig, 10. The position of the handleand lever 25 is illustrated in Fig. 7. To lock the lid the handle 6 isrotated so that the lever 25 rotates clockwise, Fig. '7, thus pulling onlinks 21 which turn levers 28 wardly. As link 30 is drawn upwardly yokeI3 rotates about pivot 22 clockwise, as viewed in Fig. 10, thus raisingpivot I4, the point at which bolt 9 is connected to yoke I3. At thistime, as shown in Fig. 10, pivot 22 is positioned above pivot I4. .Aspivot I4 rotates clockwise about fixed pivot 22, bolt 9 is drawn towardthe left and upwardly, Fig. 10, which causes the bolt head I I] to swingdownwardly into engagement with the keeper I9, as shown in Fig. 11.Further rotation of yoke I3 causes the lid Ito be pulled first inwardlyuntil pivot point HI is on the same level as pin 22, Fig. 11, whereuponfurther clockwise rotation of yoke l3 causes the lid I to be drawndownwardly into tight engagement with the Weatherstrip 4, as shown inFig. 8. It should be noted that after the hook l engages striker I9 thatbolt 9 rotates about pin l4 relative to yoke I3. In final lockedposition pivot point I4 is over the center line passing through thecenter of pivot 22 and the point at which bolt head l0 contacts striker35, see Figs. 5 and 8. Due to this over center locking arrangement anyattempt to force the lid I open merely tends to rotate yoke I3clockwise, Fig. 8, thus tightening the interengagement between the bolthead and the striker. The bolt can only be disengaged from the keeper l9by rotating yoke l3 counterclockwise, Fig. 8, to again bring pivot M tothe left of center, that is, a line passing through pin 22 and the pointat which the bolt head It interengages the striker, as illustrated inFig. 8.

In the modified form shown in Figs. 12 and 13 there is provided asimplified form of connection between the levers 23 and the yoke l3. Inthis form of the invention the support plate 48, corresponding to plateI, is provided with a flange 4|. Pin 42 is riveted at one end to flange4| and carries a bushing 43. Yoke I3 is rotatably supported on the outerend of pin 42. Pivot 42 corresponds to pivot 22 of the principal form ofthe invention. Link 44, corresponding to link 39, is pivotally connectedat one end to lever 28' and the It will be noted that when the bolt headI0 is interengaged with the keeper I?! that the bolt 9 swings about thekeeper [9 as a center during the final locking movement of the bolt andduring the initial opening movement of the bolt.
